无法访问控制器中的 current_user 以保存关系

Question

我有一个 Rails 6 项目，我 Citusdata/activerecord-multi-tenant gem 来处理基于行的多租户我正在尝试为用户创建一个时间表

因为现在我无法访问 current_user 来保存关系。我的控制台输出根本没有帮助：

它正在将关系连接到帐户模型并自动保存我的 account_id，但无法收集 user.id 或 current_user.id

我可以在新块和创建块中放置一个 byebug，但是当我在下面传递 byebug 时 @time_sheet.save 它返回为 nil。

我卡在这里了，不知道哪里出了问题？我过去做过很多这样的事情。

以下是所有设置的方式：

class User < ApplicationRecord
  extend FriendlyId
  friendly_id :username, use: :slugged

  multi_tenant :account
  belongs_to :role

  has_many :time_sheets
end

class TimeSheet < ApplicationRecord
  multi_tenant :account
  belongs_to :user (user_id in schema)
end

class TimeSheetsController < ApplicationController
before_action :authenticate_user!

  def new
    @user = current_user
    @time_sheet = TimeSheet.new
  end

  def create
    @user = current_user
    @time_sheet = TimeSheet.new(time_sheet_params)

    respond_to do |format|
      if @time_sheet.save
        format.html { redirect_to @time_sheet, flash: { success: "#{@time_sheet.start_date} - #{@time_sheet.end_date} has been sucessfully created." } }
      else
        format.html { render :new }
      end
    end
  end

end

我的新时光sheet表格

<%= form_for(@time_sheet, :html => { class: "flex w-full items-center mt-64" }) do |f| %>
<% if @time_sheet.errors.any? %>
  <div id="error_explanation">
    <h2><%= pluralize(@time_sheet.errors.count, "error") %> prohibited this user from being saved:</h2>

    <ul>
      <% @time_sheet.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
    </ul>
  </div>
<% end %>
  <div class="w-full text-center">
    <p class="text-3xl text-primary-700 mb-16">New Time Sheet</p>
    <div class="flex flex-wrap w-full justify-center">
      <div class="w-1/4 mr-3">
        <%= f.label :start_date, "Start Date", class: 'form-label text-left' %>
        <%= f.date_field :start_date, class: 'form-input w-full' %>
      </div>
      <div class="w-1/4 ml-3">
        <%= f.label :end_date, "End Date", class: 'form-label text-left' %>
        <%= f.date_field :end_date, class: 'form-input w-full' %>
      </div>
    </div>
    <div class="flex w-full justify-center">
      <div class="w-1/4 mt-6">
        <%= f.submit "Start Period", class: "p-3 w-full bg-green-800" %>
      </div>
    </div>
  </div>
<% end %>

我的控制台输出：

Answer 1

看起来您在创建 time_sheet 时没有正确传递 user_id。通过将 current_user id 合并到您的 time_sheet_params 中来更改您的新方法以包含它，如下所示：

@time_sheet = TimeSheet.new(time_sheet_params.merge(user_id: current_user.id)
